Blood type in humans is controlled by how many alleles?
Blood type in humans is controlled by three alleles at the ABO gene locus on chromosome 9. These three alleles are responsible for determining the blood types A, B, AB, and O. Each person inherits one allele from each parent, resulting in various blood type combinations.
Multiple alleles can be studied only in individuals?
Multiple alleles can indeed be studied in individuals, particularly through genetic analysis to determine which alleles are present in a given locus. This involves examining the different forms of a gene that can exist in a population, known as alleles, and how they interact to produce a specific trait or characteristic in an individual. This can provide insights into genetic diversity and inheritance patterns within a population.
How many alleles do your gametes have?
Gametes should contain one allele for each gene locus. This means that gametes will have one allele for each of the genes on the chromosomes they are carrying. It is estimated that humans have about 20,000-30,000 genes - meaning each gamete would therefore have 20,000-30,000 alleles.
How does polygenic trait differ from simple inheritance?
Well polygenetic inheritiance are traits that is controlled by multiple genes, so for one trait you may have more than two gene controlling it, human eye is an example. For polygenetic inheritance you cannot do a pedigree and calculated the percentage. For mendelian inheritance it all about two alleles for one trait where one is definetly more dominant over the other, it is much simpler than the polygenic trait and can be calculated through a pedigree.
When a trait has more than two alleles how is the trait inherited?
When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance. Many quantitative characters have polygenic inheritance. Inheritance of blood groups is an example of polygenic inheritance in human being.When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance.

About how many genes do horses have?
An individual Thoroughbred cannot have more than two different alleles for each gene locus, one on each chromosome. How many alleles are available at a certain gene locus is variable based on what the gene controls and how many alleles are available and their frequency in the population.
What is the name given to genes that have more than two alleles?
Polymorphic locus or polymorphic gene. Many geneticists use the term locus (plr. loci) for a gene (i.e. section of a chromosome)
How many alleles in each locus in a human cell and why?
In a human cell, each locus typically has two alleles, one inherited from each parent. This diploid nature allows for genetic diversity and variation within a population. However, in gametes (sperm and egg cells), there is only one allele per locus due to the process of meiosis, which reduces the chromosome number by half.
What id genetic variation?
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population

What are some examples of allele's?
Multiple alleles means that for a specific locus on a chromosome there can be 3 or more forms of that gene (allele). Only one allele can be inherited because they are found on homologous chromosomes. Height is not a multiple allele because it is associated with many genes on several chromosomes (plus environmental factors) so this would be polygenic inheritance. Multiple allele trait is the ABO group. The allele for A B or O (3 alleles ) is found on the same locus, therefore only one of them could be inherited EXAMPLE: DNA

How many years for locus comes back?
Locus reveals he has been gone for a year in Season 15 of Red vs. Blue.
How many copies of alleles do organisms carry?
It depends on the organism but humans have two alleles.
